Subject: | NSA/SONDE/C1 - Increased precision for alt, dp, pres, rh, tdry |
DataStreams: | nsasondewnpnC1.b1 |
Description: | The output precision of the following variables was increased 20060929: alt changed from 1m to 0.1m dp changed from 0.1degC to 0.01degC pres changed from 0.1 hPa to 0.01 hPa RH changed from 1%RH to 0.01%RH tdry changed from .1degC to 0.01degC Note that the increase in precision does not necessarily imply an increase in accuracy. Users are cautioned to continue to use their best scientific judgement when using these or any other data. |

Subject: | NSA/MET/C1 - CMH failure |
DataStreams: | nsametC1.b1 |
Description: | Starting 14:17 GMT on 12/4/2011 the CMH Dew Point began reporting missing value, CMH relative humidity was flat-lining at 100% and CMH saturated vapor pressure was flat-lined at a high value. This condition continued very intermittently for several months. Issue was frosting and a failed ventilation fan. |
